나노 구조물을 이용한 투명한 극소수성 필름 제작 및 특성 연구

Abstract

Transparent and super-hydrophobic films are fabricated by using PDMS method and silane process, based on anodization process in phosphoric acid. Contact angle tests performed to obtain the contact angle of each film according to anodizing time. And transmittance tests also performed to obtain the transparency of each TPT replica film according to anodizing time. Characteristics such as contact angle and transmittance were investigated in drop shape analysis system and UV-spectrometer. Pore length of AAO nanohoneycomb structures increases with increasing anodizing time. And also contact angle increases with increasing anodizing time because increasing pillar length can trap more air between TPT replica film and a drop of water. But transmittance decreases with increasing anodizing time because increasing pillar length can cause scattering effect. As a result of this study, we know that the pillar length and transparency are competitive relationship.
